BMW’s Unique Approach to EVs: Efficiency Over Bigger Batteries

BMW challenges conventional EV design by rejecting larger batteries. Frank Weber explains why efficiency, aerodynamics, and charging speed matter more. Read the full analysis.

When it comes to electric vehicles, most manufacturers are racing to deliver the longest possible range. But BMW is taking a different approach: instead of chasing larger batteries, the company is focusing on efficiency. And judging by sales figures, this strategy is paying off.

BMW’s head of research and development, Frank Weber, firmly believes that increasing battery capacity doesn’t always make sense. In an interview with Automotive News, he argued that the push for the so-called "holy grail" of EVs – 1,000 kilometers (621 miles) of range – is unnecessary given real-world driving habits. According to BMW's internal data, most EV owners rarely travel such long distances.

Rather than making batteries bigger, BMW is working to make them better. Its next-generation Gen6 battery technology, set to debut in Neue Klasse models, promises 20% greater energy density and 30% faster charging times. In practice, this means that 200 miles of range can be added in just 10 minutes.

BMW engineers have also focused on aerodynamics: the Vision Neue Klasse X concept boasts 20% lower drag coefficient compared to current models, further enhancing efficiency and range without requiring massive battery packs.

Despite its unconventional strategy, BMW’s EV sales are on the rise. In 2024 alone, the company sold 426,594 fully electric vehicles, marking a 13.5% increase from the previous year.

An analysis of real-world data supports BMW’s stance. In the UK, the average daily mileage for drivers is around 20 miles, which aligns with BMW’s argument that most users don’t require extreme range.

But the big question remains: will this strategy hold up in the long run? With the rapid expansion of fast-charging infrastructure and ongoing improvements in energy efficiency, BMW’s bet on smaller, more efficient batteries could be validated. However, if the market continues to demand maximum range, the company may need to adjust its approach.

For now, BMW has proven that it’s willing to go against the grain. And so far, it’s working.
